    Ephestia figulilella, Gregson. (Figs. 49-51). ‘Figs. 49-51. Ephestia figulilella, Gregson.—(49) Head. (50) Meso-ventral view of left mandible. (51) Antenna.. Only a single bred specimen has been examined, which is 8 mm. long and 1:3 mm. broad. It is very close to E. cautella, and, until more specimens are available, cannot be satisfactorily distinguished from the latter species. The pinnaculae of the ab- | dominal setae are more feebly pigmented than in L. cautella, and epsilon of 8 is separated from the spiracle by a distance about equal to the diameter of the spiracle, whereas in F. cautella epsilon is nearly always separated from the spiracle by distinctly less than the diameter of the latter. The puncture between setae i and. i il of the head is relatively much err in E. figulilella than E. cautella.
